Reply To: Seal Upper Crankshaft Bearing Evinrude 18 HP 1960

Hi. I will definitely not put an O-ring on the upper bearing, but I did put a very thin layer of Loctite 518 anaerobic sealer between the seal and the groove in the bearing where the new seal is pressed in. I sprayed just a little Loctite 7649 primer first since it might be required for the 518 sealer to work. I did this to prevent oil from travelling between the seal and the bearing groove. (Hope my English is understandable, this is not my primary language)

Wouldn’t it be a little tricky to put 518 sealer between the bearing and the crankcase halves? I’m afraid this might start getting trouble with the oil drain holes. Any thoughts on how to avoid sealing the drain holes when putting sealer between the bearing and the crankcase halves?
